RAILWAY-CAR DOOR.

. Application ala January e, 1923. seriai No. 610,962.

T o all whom, t may concer/n Be it known that I, Pintor M. ELLio'rr, a citizen of 'the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and` useful Improvements in` Railway-Car Doors, of which the following is a specification.

This invention relates to railway car doors constructed o'f sheet metal sections with marginal reinforce members of structural shapes, and has for its object to provide a door which, while insuring necessary security and durability in use and convenience in applying it to railway cars, will be of simpler construction, of lighter weight, and vcheaper to produce than previously known oors.

top guiding and confining The invention proceeds upon the princi' ple of making the main oody of the door of a plurality of sheets lap jointed together and having distributed over the areas of these sheets, and therefore over the area of the door as a whole, stiffening' corrugations at relatively wide-distances apart, `which leave the main area of the .door in a single plane; these corrugations being terminated short of the vertical margins of the door;`

'the top and bottom margins being strengthened by flat reinforcing plates approximate\ ly coeXtensive with the width of the door;

and the vertical margins beyond the horizontal corrugations being reinforced by longitudinally corrugated strengthening ribs with, continuous flanges that embrace substantially the whole area between the ends of the horizontal corrugations and the ledges of the door; vertical marginal reinforcing bars being lapped over the top and bottom marginal plates in 1 order to dissipate any line of fleXure of the body plates that might develop at the inner edges of the top and bottom marginal plates. The invention consists of these and other features to 'be hereinafter described in detail, either severally or in various combinations -that are hereinafter pointed out in the claims.

In the accompanying drawings- Figure 1 is a side elevation of a portion of a freight car havinga door embodyingin its construction the several features of the present invention.

Fi ure 2 is a section on the line 2x` of Figure 1; and l t longitudinal f attaching' of the corrugations Figure 3 isa section on the line 3X-3X of' Figures 1 and 2.

1 represents a car body provided with a rail 2 that receives, a hanger' or hangers 5 from which to support a door upon said rail, anda represents a bottom guide for assisting-in conlinement of adoor relatively to the doorway '5, of the car. i I

6 represents the doorV confined by the hanger and bottom guide referred to, in position for sliding into and out of closing relation to the doorway series of plate sections`6a, 6", and 6, each having a horizontal dimension equivalent to the width of the door, united by horizontal lap joints 6x, and collectively developing the height of the door. Each plate section is formed with corrugations'?, preferably 'two 5. This door comprises a in number, a't relatively wide-distances apart outer attaching flange 12 and inner -attaching flange lwhich are riveted tothe for- Ward margin of the sheets 6, 6b, and 6; and thecorrugation barA 11 has inner attaching flange 14 and outer attaching-flange 15 riv-V eted to the vrear marginal portion of the sheets.

flanges on either side thereof, occupy substantially the entire space between the ends 7 and the front and rear ledges of the door, so that they stilfen all those portions `of,the door-which vare not -stilfened by the horizontal corrugations 7p.

Moreover, horizontal reinforcing plates 16` The corrugation bars thus made upA of a single corrugation with attaching' and 17, extending across the door respectively at top and bottom thereof, are overlapped by the vertical marginal corrugat-ion bars 10 and 11 in a manner to form with the latter a substantially rectangular frame sustaining the body sheets of the door. The vertical corrugations of bars 10 and 11ter -minate short ofthe top and bottom margins of the door but lap well over on to the reinforcing plates 16-17. At top the hang- .one side of the corrugation bar, and at botof ers 3 are riveted tothe reinforce rib 16, at

vteniritl'iere is left a free space of suificient.

'. lOand 11,. to provide limited facel bearings that'receive the bottom guides 4 when the' door is closed, and canse the door to be pressed into pilfer-proof and weather-proof` closure against the face of the door; the

v cavities left by said swells being closed on the rear by the reinforce plate 17 which l thereby prevents escape of small subdivided ycargo as well as the introduction of a tool or instrument in an attempt to pilfer. In vaddition to the framing and reinforcingfmemberslreferred to, the front and rear margins' are` preferably providedwith base plates18, '19 for the rivets which secure the corrugation bars, andthe front margin is provided with an angle bar striker 21 while the rear vertical margin Vis equipped with sealingflange 22, ofwhich the former is held in place by the same rivets 23 that vhold the` corrugation bar l and the rivet- "in'g plate 18, while the latter constitutes an 'integral extension of the corrugation bar'11.

` Corrugation bar 11 sustains thedoor sheet against flexing stresses on vertical lines, de-

veloped by the impingement of the weatherprooing flange v22 against. the striker 22a. The shape of the corrugation 1l is particularly effective to this end by reason of the straight'form ofthe rearside of the corrugation and its. angular relation to the plane of the door sheet. The angle bar 21 ,not only provides a strong vertical `reinforcing member but, together with the other vmembers at the forward edge of thefdoor, develops a double weather-proofing arrangement, in

' that it .forms a vertically d'isposedangular air channel between its outstanding flange 21and the forwardly inclined side. of the corrngation '10.' This air space helps to de- -fleet rain, dust or other foreign matter which Inight otherwise enter around. the

front edge Iof the door, and thev outwardly" presented flange affords a convenient means Athrough 'which to and closing'it,A
